To all whom it may concern:

Be it known that I, Lnwrs E. FEIGHTNER, a citizen of the United States, residing at 715 South Broadway, Lima, county of Allen, and State of Ohio, have invented certain new and useful Improvements in Steam-Engine Mountings for Geared Locomotives, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to the class of geared locomotives, in which the weight is carried upon truck-wheels having gears attached thereto, and such gears connected by a suitable line-shaft and couplings to a longitudinal crank-shaft. In such locomotives, it has been common to use upright engines and to fasten the steam cylinders by bracket-feet and bolts directly to the firebox of the boiler thus necessitating the disconnection of the cylinders from the boilers whenever it becomes necessary to lift the boiler from the frame, and it is the object of the present invention to furnish supports for the engines wholly upon the side-frame of the locomotive, so that the boiler can be applied to and removed from the frame without disturbing the engines or unbolting the cylinder connections.

This object is attained the side-frames of the locomotive of sufficient depth to attach the cylinders and the to the upcrank-shaft bearings respectively the brackper and lower edges of the frame, ets which support connected by crosshead guides in such manner as to strongly brace those parts together, and hold them rigidly upon the frame. The locomotive frame is preferably made of plate-girders and one of them extended upwardly at the side of the locomotive boiler materially above the bottom line of the same and possessing sufficient breadth to support the parts firmly when the cylinder brackets and the crank-shaft bracket are attached thereto. The plate-form of girder affords a flat surface intermediate its edges to which the feet of the cylinder brackets can be attached as well as to the upper edge of the girder, thus securing a very firm support for the cylinders, in connection with the brace afiorded by the crosshead guides, which form a part of such cylinder brackets and by making one of both of these parts being which are attached at their lower ends to a horizontally extended bracket having bearings for the crank-shaft.

The upright engines in geared locomotives are commonly arranged at one side of the frame to operate the gearing at the one end of the trackaxles, and the construction illustrated herein thus necessitatesthe disposition of the boiler center at one side of I the truck-centers, and the arrangement of one of the locomotive frames below the bottom line of the boiler and the other frame above the said line. The vertical engines being attached to the higher of the two frames, has ample support independent of the'boiler, and all the space above the frames is thus entirely clear so that the boiler can be lifted therefrom Without any disconnection of the englnes.

In the drawing the invention is illustrated in a loco-motive having two eight-wheel trucks, Figure 1 showing a side elevation of the locomotive; Fig. 2 a front elevation of the cylinder, and cranlebearing attachment. Fig. 3 is a side elevation of the same with a section of the locomotive side-frame. Figs. 2 and 3 are upon a larger scale than Fig. 1. Fig. 4 is a section of the locomotive frame on line 4- in Fig. 1 with the engines and 7 upon two trucks by bolsters c and (Z, the

ends of the side-frames being at the same level, to receive the said bolsters. The center line m-m of the fire-box is disposed considerably at one side of the center line g of the truck, to balance the weight of the engines represented by the cylinders e and crank-shaft f; which are attached to the outer side of the side-frame A. Fig. 4 shows the forward truck wit-h the swivel plate 0 of the bolster 0, through which the line g 2 is drawn. This relation of the boiler and trucks brings the crank-shaft f in a line with the line-shaft f which is connected by gears g with the truck-wheels h. This disposition of the boiler necessitates the bending of the thereto by .bolts 9.

side-frame B downward as indicated by dotted lines in Fig.1, to pass under the firebox of the boiler and thus support the same.

The side-frame A is disposed at one side of the fire-box, almost wholly above the bottom of the same, and thus lies about midway between the cylinders e and the crank-shaft f, so that both can be firmly attached thereto. An engine is shown, with three cylinders fastened separately to the side-frame A by cylinder brackets, and the side-frames are shown of plate-girder form, with angle-irons at the edges connected to top and bottom plates a and a The crank-shaft is shown carried in a horizontally extended bracket 1' having four bearings for the crank-shaft, with spaces between the'bearin s for the cranks 7c. The

crank-shaft bracket 2' is shown with a foot Z attached to the bottom plate of the girder A,

and a flan e Z attached to the an le nextv such plate, and it is provided upon the top with seats m for the feet of crosshead-guides ma. Each pair of crosshead-guides is formed at the top in one piece with a circular flange 0 to which the bottom of the cylinder 6 is bolted, and the inner crossheadguide a is formed with a horizontal. lug 7) which is secured by bolts 9 to the top-plate a of thegirder a. The same guide is formed with a vertical foot 7) which fits the face of the girder plate between the angle-irons, 7 The crosshead-guide with the lug 79, foot p fiange 0, and bottom frame 11?. forms an integral cylinder bracket. The bottom ends of the ,crosshead-guides have feet 122/ connected by a fiat frame m and the feet bolted upon the seats at of the crank-shaft bracket i; which thus ties all the crosshead-guides together, while the connec tion of the crossheadeguides with the cylin ders and the crank-shaft bracket braces each of those parts firmly to one another and to the girder A, as the lug p and foot 2) form a part of the inner guide 72.

Reference to Fig. 4- shows that the engines are disposed wholly outside of the side-frame A and connected solely thereto, while the boiler sets upon the inner side of the said frame, entirely .clear of the engines, and thus adapted to be lifted from the frames without displacing any part whatever of the engines.

The connection of the engines with the side-frame A by means of cylinder-brackets and a crank-bracket, which are bolted to gether as well as to .the side-frame, holds all the parts securely=in their working position, while avoiding the bolting of the cylinders to the fire-box which has been common hitherto.

The axis 2 of the cylinders and crank-shaft is, at the top, inclined outwardly from the side-frame A and the fire-box. thus making some space above the edge of the side-frame in which the fire-box can be extended by curving its upper side 5 toward the cylinders, thus widening the upper part of the fire-box just below the crown-sheet b and mounted upon the outer side of the sideframe A, and I have therefo-re'claimed the same in connection with such mounting of the engines.

Having thus set forth the nature of the invention what is claimed herein is:

1. In a geared locomotive, the combina, tion, with two side-frames and a longitudinal boiler supported removably thereon, of vertical engines projected upward by the side of the boiler and supported wholly upon one of the side-frames to permit the removal of the boiler from the frames with-- out disturbing the engines.

2. In a geared locomotive, the combination, with two side-frames and a longitudinal boiler supported removably thereon, of a longitudinal crank-shaft having bearings at one side of the frames and vertical englue-cylinders attached to one of the sideframes above the crank-shaft and wholly clear from the boiler to permit the ready removal of the boiler from the frames.

3. In a geared locomotive, the combination, with two side-frames, trucks sup-porting the frames and having the truck-wheels supplied with gearing, and a locomotive boiler supported removably upon the frames, of a crank-shaft with bearings at one side of the frames, vertical engines projected upwardly at the side of the boiler firebox, and brackets attached to one of the side-frames and supporting the engines and crank-shaft thereupon.

4:. In a geared locomotive, the combination, with two side-frames and a longitudinal boiler supported removably thereon, of a crank shaft, a bracket upon one of the side-frames with bearings for the crank shaft, a bracket attached solely to the said side-frame with steam-cylinder supported thereon, and crosshead guides connecting the steam-cylinder and the crank-shaft bracket.

5. In a geared locomotive, the combination, with a longitudinal boiler, of a main frame including a girder at one side of the boiler, a longitudinal crank-shaft with bracket having bearings therefor and attached to the lower edge of the said girder, steam-cylinders with brackets supporting the same upon the upper edge of said girder, and crosshead-guides connecting the said cylinders and crank shaft bracket.

6. In a geared locomotive, the combination, with a longitudinal boiler, of a main frame having a'plate-girder at one side of the boiler, a crankshaft with a plurality of cranks, a horizontally extended crank-shaft bracket attached to the lower edge of such girder and provided with bearings between the cranks for the said shaft, steam-cylinders corresponding to the said cranks, and brackets attached to and supporting them upon the upper edge of the girder, and said brackets provided with crosshead-guides attached to the cylinders and to the said crank-shaft bracket.

7. In a geared locomotive, the 'combination with a longitudinal removable boiler, of a main frame having a plate-girder at one side of the boiler, a longitudinal crankshaft, a horizontally extended bracket attached to the lower edge of such girder with bearings between the cranks of the said shaft, steam-cylinders corresponding to the said cranks with brackets attached to and supporting them upon the upper edge and face of the said girder, and crosshead-guides formed in one piece with the said cylinderbrackets and connected to the crank-shaft bracket.

8. In a geared locomotive, the combination, with a removable locomotive boiler having the fire-box at one end, of two sideframes having their ends at the same level and provided with bolsters, and trucks to support the same, one of the side-frames be ing bent downwardly to the bottom of the said fire-box and the other side-frame extending along the outer side of the fire-box, and vertical engines including the crankshaft and bearings attached exclusively to the said frame which is extended outside of the firebox.

9. In a geared locomotive, the combina tion, with a removable locomotive boiler having the fire-box at one end, of two sideframes having their ends at the same level and provided with bolsters, and trucks to support the same, one of the side-frames being bent downwardly to the bottom of the said fire-box and the other side-frame extending along the outer side of the fire-box, and vertical engines including the crankshaft and bearings attached exclusively to the said frame which is extended outside of the fire-box, and the upper part of the said fire-box being curved outwardly at one side above the side-frame which carries the said engines, whereby the fire-box is widened in its upper part, thereby afiording more space for combustion and for the insertion of flues.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
